I've been able to do multisig between two addresses from electrum and one from bitcoind.

I've created an address like this.

Wallet 1 (Electrum)

addr: tb1qp23cmwgn8qnv8cg5h595ne7nuvlvjhpxssee4d

Wallet 3 (bitcoind)

pubkey: 0361ac153cfc0c5cefb74fa904ca83105ccdcbaa3c1ebb8266a03212619ae1006a

privkey: cVvXTPL6ozGX9ckrNQ7gEudkPnEb6sPdtKPFEsLaQG38JdX1TXqn

Here are the infos of those wallets.

}

And created a legacy multisig address. After funding the multisig address, I created a spend transaction.

After signing the transaction with another wallet, I was able to broadcast the transaction with no hassle. Here's the result.

https://blockstream.info/testnet/tx/3420c45740088a85b2ae2ec439e1bafe3485358eb6f97cb73730b21ae69eac2b

So, with this method, I tried again but this time with bech32 address to save fee.

What's wrong with my method? What do I have to do if I want a bech32 multisig address?

Finally, I got the spend transaction. I signed it with another wallet and tried broadcasting it.

This wallet filled the scriptSig instead of the witness.

Here is a step-by-step P2WSH multisig I made on regtest:

Generate two addresses:

$ bcreg1 getnewaddress
2MsPUyivVzHR236LybpdVN7JUaTETQfGwYM
$ bcreg1 getnewaddress
2MyTveMpMuXLVsgEuwACM6ZuRsH5GS2TuFk

For each address, get the public key:

$ bcreg1 getaddressinfo 2MsPUyivVzHR236LybpdVN7JUaTETQfGwYM |grep pub
$ bcreg1 getaddressinfo 2MyTveMpMuXLVsgEuwACM6ZuRsH5GS2TuFk |grep pub

And create a multisig script with those:

$ bcreg1 createmultisig 2 "[\"0327c98b3913b9f4e17f2b783ecb632a065067afda3f7619c6f3cf8b7450f24412\",\"026d1ab02d0c1bad3319d1d77c45187e30ef1145094d6e8c18f4a0f0b897f6a11d\"]"

Fund an output paying to that script:

$ bcreg1 sendtoaddress bcrt1q49mxte3mzw8e2j8k7gryvg4exezfjsmeuw80xjp3704lhnmxfz6s9zl7gc 1

Create a transaction spending the above one (I generated another address for this transaction's output):

$ bcreg1 createrawtransaction "[{\"txid\":\"e46828bf1e6eb0f465bb2e89ae76d7cc7acb71bbddff64c7911fb4717252a549\", \"vout\":0}]" ["{\"bcrt1qnc6kuzpmumw5qk07yf89surujdwrunyqxjyyed\":1}]"

Get the private keys of the two pubkeys from which you created the multisig:

$ bcreg1 dumpprivkey 2MsPUyivVzHR236LybpdVN7JUaTETQfGwYM
$ bcreg1 dumpprivkey 2MyTveMpMuXLVsgEuwACM6ZuRsH5GS2TuFk

Then sign the transaction with both private keys (You missed that step by specifying only one key):

$ bcreg1 signrawtransactionwithkey 020000000149a5527271b41f91c764ffddbb71cb7accd776ae892ebb65f4b06e1ebf2868e40000000000ffffffff0100e1f505000000001600149e356e083be6dd4059fe224e58707c935c3e4c8000000000 "[\"cRQN9dxDNsPbZygyto9sjvnMFDu8hb7ghSFJwu8dJk3f1ZNVoQv3\", \"cSJD9VfWgfpgPE9K6dAZLXsUHG4Y5e7cyhBypPsjnzBNP5iuUjXv\"]" "[{\"txid\":\"e46828bf1e6eb0f465bb2e89ae76d7cc7acb71bbddff64c7911fb4717252a549\", \"vout\":0, \"scriptPubKey\":\"0020a97665e63b138f9548f6f2064622b93644994379e38ef34831f3ebfbcf6648b5\", \"witnessScript\":\"52210327c98b3913b9f4e17f2b783ecb632a065067afda3f7619c6f3cf8b7450f2441221026d1ab02d0c1bad3319d1d77c45187e30ef1145094d6e8c18f4a0f0b897f6a11d52ae\", \"amount\":1}]"
